Talvez debería tentar con algunhas variantes ortográficas:
communication relations » communication relational, communication relating, communications regulations
based dispersion » wave dispersion, gas dispersion, based discussion
based dimension » basic dimensions, based extension, based diffusion
array ang » arrays ang, array along, array range
arrays a » arrays _

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication relations ((based dimension) OR (based dispersion)) ((array ang) or (arrays a))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication relations ((based dimension) OR (based dispersion)) ((array ang) OR (arrays a)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication relations ((based dimension) OR (based dispersion)) ((array ang) or (arrays a))".
• Adding a wildcard symbol may retrieve word variants: communication relations ((based dimension) OR (based dispersion)) ((array ang) or (arrays a))*.
